MVPA - HPC unsmoothed

Another potentially interesting question we can try to answer is how much face representation we see across the task. In order to do so, we’ve trained a linear SVM classifier within subjects on the data from the smoothed FFA localizer to classify signal into faces, objects and scrambles. We can then apply that classifier to various facets of our data. For each of these analyses, we will look at the probability of the classifier predicting a face. If the classifier does indeed predict a face, we score that TR with a “1”, otherwise, it gets a “0”, meaning chance becomes 1/3 = .33.
First, we will apply it to each TR of individual trials. Trials are split into 4 bins based on accuracy and load, and averaged over those measures to create a single time course for each category. The classifier was also applied to each TR of a “template” for each condition. In this analysis, all trials in a given condition were averaged to create a prototypical example for the category. The classifier was then applied to those averages.
We can then look at the probability of classification across subjects. First, we look at it across all subjects, but then we can look at it across our working memory capacity groups.
Finally, we will relate these neural measures to behavior, both averaged over time and for each TR.

On average, we were able to classify faces with 42.2% accuracy (statistically significantly different from chance = 0.33). The classifier was trained on data from an independent FFA localizer. Data was extracted from the bilateral hippocampus. From that mask, the top 100 voxels based on the faces vs objects contrast in the overall subject GLM were selected as features for the classifier. The data used to train the classifier were shifted by 4.5 seconds to account for the hemodynamic delay.
A linear SVM classifer was used; the localizer task was split into 6 blocks of stimuli. These blocks were used in a pre-defined split for cross validation, where one block of each stimulus type was held out as a test set. Data were normalized within the training and test sets separately. Within this training set, another cross validation process was repeated to tune the cost of the model over the values [0.01, 0.1, 1, 10]. The best value of the cost function was used for each cross validation to score the classifier on the test set. The best classifer was also used to predict face presence at each TR during the DFR task.
We can see that there are a number of subjects for whom the classifier works below chance - we’ll remove those from the analysis

The shape of the time course is different here than it was for the fusiform region - here, we’re well below chance for encoding, but start to see a significant probability during delay (starting around TR 8) and the probe.
From individual trials
Here, we’re seeing a similiar pattern to the fusform, where we see peaks of decoding accuracy around the encoding period and then probe period. However, unlike the fusiform, we’re also seeing above chance accuracy for all trial types during the delay period. We also see that during encoding, high load trials (regardless of accuracy) show a higher probability of having a face decoded than low load trials. There are no differences between trial types, however, during probe.

Individual Trials
Averaged over time
If we look averaged over time, we see a significant positive correlation with omnibus span and the difference between classification at corect and incorrect low load trials. We also see significant negative correlation between high load accuacy and decoding at low load incorrect trials, and between BPRS and classification at high load incorrect trials, and a positive cprrelation with the differnce between correct and incorrect at high load trials.

Across time
If we look at the patterns over time, we can see that BPRS tends to be negatively related to classification during encoding and probe periods. There is most correlation with accuracy during the encoding period. Span generally has a low correlation with classification probability.
Next step is to pull out some of these correlations and see if they’re significant.

There is a significant positive relationship between the difference between correct and incorrect trials at low load and span.
There is a significant negative relationship between classification accuracy at low load incorrect trials and accuracy positive relationship between the difference between correct and incorrect trials at low load and accuracy
There is also a trending correlation for the difference between correct and incorrect at high load trials and BPRS (excluding the outlier).
